Abstract ： Using Ф-mapping method and topological current theory, we get the topological structure and the topological quantization of topological linear defects and point out that the topological quantum numbers of the linear defects are described by the Winding numbers of Ф-mapping which are determined in terms of the Hopf indices and the Brouwer degrees. All the topological linear defects are generated from the zero points of the Ф-mapping.
